Thus-the machineoftl'l'e" presentiinvention. requires no speciali foundations* forfitsy support; and in fact may; ifj desired; be mounted on an ordinary desk;

The portable photo-comp'osing'A machine dis'-Y closed"i herein is useful' for' av Wide variety of purposes. For example; many of the oriental and middle eastern* languages: have alphabetscom-- posedy of a veryV large1 number' ofl individual chareacters, outstanding examples of suchy languages* being Chinese and'Ja-panese. Insuchcases; keyboardcomposition is wholly impractical` and"vr hand composition must bel used. The' present machine provides4 aconvenientV Way of'` produc-'- ing high quality composition in such cases'at a' reasonable'cost, Along the saineI4 line thecomposition of' mathcmaticali and other scientific subject matterfrequ'ently requires the use of' a: large number of specializedA characters andl therA present machine' is especially useful forthistyp'e" of Work aswell The present macl'iineisv also useful conne'cltion with advertising composition where relatively'small amounts of 'text are toV beusedinconjunction with illustrations. In" such casespspecial type faces arellikelyv to' be used andwith the" presentmachine flexibility and high quality com'- position can be readily achieved. Similarly theAl machineV is useful" in preparing various'business forms such as ruledforms which may or mayv not; contain small amounts of text thereon. Anillus.- trative method ofpreparing. such forms'is disclosed in. Freundapplication Serial.No..209`,5.7`0` l filed February.- 6 ,L 1'951.

The presentv machine`A is. useful. for a. wider varietyY of special printing.. jobs. such. as greeting card's matchbooks labels. and stripping mate-L ria i`. ef lines. ofi text. or. singleWordsy tofbe4 ap-1 pliedfto mapsfandithe, like.l Moreover. itis useful?. for composing display headsv ofthet-ypawhich,z When produced by. type-casting methods.. require a, special'. machine. for their. productionA With. the present. machine, much higher quality com.V position canbe.: achieved than vvith=-v the-,special type-casting machines. presently, available for.- this purpose. Moreover the re-touching that-is frequently requiredwhere. display heads areiproduced'lfromcast leadltyipe is unnecessary with-the: present machine.

In certain cases the present machine can be usefully employed in conjunction with a group of keyboard-type photo-composing machines. Thus where a group of keyboard-type machines is operating on a production basis, the smaller machine can be conveniently used to compose corrected lines and thereby avoid interrupting the production schedule of the larger machines.

The machine disclosed in the present application is in many of its details substantially the same as the machine disclosed in Freund et al. Patent 2,552,882, and since no useful purpose would be served by repeating herein the rather lengthy description of these details, frequent reference will be made in the following description to this Freund et al. patent. As described in Patent 2,552,882, the characters to be photographed are mounted in matrices such as that shown in Figure 2 of the present application. Composition of the desired type matter is effected by assembling matrices bearing the proper characters into a line of desired length and then individually photographing on a sensitized surface the characters of successive matrices of the composed line to produce a line of type matter on the sensitized surface, 'I he matrices have a thickness that is proportioned to thek set-wise Width of the characters they bear, and hence the 'amazes matrix: thicknessi can. be used to: regulate film. mcvementto secure proper: spacing, of the char-` acters in the composed line.

Brief descriptz'on.-y ofmachz'ne:

Theoperation ofthe. machine will` first be.. genorally. described'. with reference to Figure. 1. ofi the. drawings andthereafter various portions of' of Figure 1, in` using the present' machine a.

line of.` matrices Mi-I. is hand composed' in a composing. device [10.1 which. is capable. of being removedv from themachine. and inserted therein ina manner described, in detail hereafter.. The composedl'ine of'matrices.M.-I is manually shifted. to the left into an elevator. l2`whi'ch is manually raisedto an upper position at which iti tripsv a line-follower releasev lever lld. As describedA in. Patent 2,552,882, trippingof the lever iligreleases a li'ne delivery lever 1.6" which is urged. to the left by a spring. i8 and is connected. to a linefollower that` pushes the composed' line of matrices from the elevator along a feed channel or track 2.2. to a justifying station 2li. As the line-follower '29. reaches the, justifying station it engagesand' is latchedto a line-lengthV determining member 2S' carriedon a feed racli 2?.

At the. justification station 2d' justifying mech.- anism generally' designated' 28 is provided which is similar to the mechanism disclosed in Freund application Serial No. 17:7.,145, iiled August 2,

1950, 110W Patent NO. 2,645,168, of July 14, 1953,

but differs therefromv in certa-in respects that aredescribed in detail hereafter. At the justifying station 24 the mechanism 28 measures the dii'erencebetween actual length of the composed lineof 'matrices andy the desired line length to determine what will hereafter be' referred to as the line shortage', and modiies the movement of thelm' in such manner that this difference or shortage-is=distributed over the line of type matter produced on the film or over a selected portion thereof, all as described in the Freund application, Serial No. 177,145. As an incident of thejjustication measurement operation the coinposed line of matrices at station 2li is urged to the left' against an end wall C that forms part ofthe camera housing.

Whenthe justification measurement has been completed, the characters on thev matrices are individually photographed by a camera mechanismv `generally' designated si) that includes a vertically movable film holder 32. To start the plfiotographing operation an accumulator bar plate 34?, shown at the top central portion of Figure l and carrying an accumulator bar 36, is manually lowered. As thev accumulator bar plate 34' approaches its lower position, it actuates a clutch that starts various operating parts of the camera mechanism. As described in Patent 2,552,882, these operating parts include a pair of' endless conveyors that transport the leading element of the line of matrices, i. e; the matrix abutting end wall 0,I from the justifying station 2d upward to a photographing position, whereat the character on the matrixk is photographedi, and then to a discharging position from which it is discharged on the accumulator bar 36. Lowering of accumulator bar plate 34 also causes various shutters forming part of the photographing mechanism tov start operating and releases thev feedrack 2'! for leitward movement.

rack 211 is connected.`- through member 2.6`

6 with'v VlineI follower- 2li. Hence thisy leftwardi movement. of.Y the. feed rack occurs., in steps as@l each. matrixfreaches end wal1eG anch is withidrawn from; the composed line..

The feed rack 2l', as described in Patent 2,552,882, is connecte-d; by aK gearan'd shaft assembly. 32 with a ver-.tical rack. llt, onA which, the nlm holder 32 normally. rests.. Thus'. the. lm. holder- 3.2. moves` downward. in4 a4 stepwise. man:- ner as each element, is,A photographed... The; amount of. downward.. movement comprising, each. stepi of.. the-nlm. holder dependsupon thesetwise width. of.. the character` being, photographed, and alsouponithe line.shortagereferredto above.. As. emalained` in. Freund application. Serial. No, 173,145, in. certain cases, as', for example where.-V tabular. matter is being composed, it is desirable that no. justifying: correction. be. applied.. to, the :tabularmatter and hencedurng .photographing of such tabular matter each, stepA movement'. of. theriilmholder. t?. is proportionedonly to.. the setwise width. of. the. character being. photo.- graphed.

Upon completion of the photographing of Vva line ofl matrices, the line-follower 20 is manually retracted, to the right by means of a knob 42" secured thereto. This retraction ofline-follower. 20 moves delivery lever I6 to the right', i.` e. to. its position as shown in Figure 1, andLal'so, through, the medium of a chain 44raisesn1mholder. 3,2; to its upper position. Feed rack` 21`i's.. al'sore-Y tracted, thus raising rack 40 toitsupper. position. to support nlm holder 32. during the nexty photo.- graphing operation. Thereafter accumulator ban plate 31H..A is raisedto disengage theclutchwhich. interconnects the photographingmechani'sm and its drive, and to lock the feed. rack 21. The; matrices which have beendischarged onaccumulator bar 36 are removed and disposedofas de.- sired. The composing device l0 provides av convenient meansfor removing the matrices from the bar 36.

The machine as showny in Figure 1. includes. variousadjusting members for adjusting thema-.- chine invarious respects. All of these` adjusting members are either disclosed in Patent. N0. 2,552,882 or will be described in detail hereafter.,A Beginning at the left-,hand side of Figure l, these.Y adjusting members include` a knob 46 whereby line-advancing movement of the film can beefV fectedupon completion of thephotographingy of: aline of elements; a lens adjusting dial: 48. whereby the degree of magnificationA of the char.-n acters of the character bearing elements can be.- varied; a gear box 50 which is exchangeable.; with other gear. boxes` to vary the relationship; between movement of feed rack ZIfand movement. of film holder 32; a release lever 52 which is movable to releasegear box 50 from its-gear and shaft assembly; a knurled disk 54 whereby the initial position of film holder 32 may beadjusted. to provide for accurate alignment of the.v left; margin of the column of type matter with..dif:AVV ferent degrees of magnification;v a vertically.y shiftable lever 56 for operating the justifying; mechanism 28; a margin control lever 58 tu.v provide for aligning a short lineof type matter.' at either the left or right margin as desired;` 'a'. switch 62 for turning' on the motorl that drives; the photographing mechanism and also energize ing the light source; a rheostat knob 60 (near the top of Figure 1) for adjusting the intensity` of the light source used for photographing; a; locking member |02 for locking they adjustablepartsfof1 composingdevice l0; anda-handfwheell 7 64 which when rotated sets an index 66 relative to a drum scale 68 to indicate the point size of the desired line and also adjusts the line-length determining member 26 to the proper position.

Hand composing device The hand composing device I is best shown in Figures 4, 6, 8, 9 and 10 of the drawings. Referring rst to Figure 4, this device includes a slotted support generally designated 80 and comprising a base 82 having the longitudinally slot 84 therein, a relatively high rear wall 86 and a relatively low front wall 88. The base 82 and walls 86 and 08 form a channel within which is positioned an assembler slide 90 having a longitudinal slot 92 therein that registers with the slot 84, and an upstanding end wall 04. The slide 90 is provided with a curved right-hand end 96 to facilitate manual movement of the slide with respect to support 80.

Mounted on the assembler slide 90 there is an adjustable guide 58 having an upstanding wall |00 aligned with the wall 94 of slide Bil. The guide 98 is adjustably secured to the slide 90 by means of a rotatable locking member |02 and astepped shoe |04. Referring particularly to Figure 6, the locking member |52 is provided with a laterally extending handle Ille` and a downwardly projecting pin |00 that is threaded into the shoe |04. The upper step il@ of shoe |04 slides in the slot 84 of support il?) and the lower step I|2 provides a flange that prevents disengagement of slide 90 and guide :from support 80. The upper step |I0 also provides a stop to limit movement of assembled slide 90 with respect to support 80 in a manner more fully described hereafter.

The steps I I0 and I I2 are of such a height that when the locking member |02 is rotated clockwise the guide 90 is securely fastened to the slide 30 but the slide 90 is freely slidable with respect to support 80. The guide S8 may be adjusted with respect to slide 90 by rotating locking member |02 counterclockwise to such an extent as to permit the pin |08 to slide freely in slot 92 of the assembler slide. The guide 93 and slide 90 are initially so adjusted as to provide a space between walls 94 and |00 equal to the desired line length. The manner of controlling this adjustment is described in the following section. When the desired spacing has been achieved, locking member |02 is rotated clockwise to fasten the guide and slide together securely and a line of matrices is hand composed in the space between the walls 94 and |60. The composed line of matrices is then inserted into the machine in a manner described hereafter.

Line-lcngth. adjusting mechanism The line-length adjusting mechanism, which is best shown in Figures 7, e and 10 of the drawings, is generally similar to that disclosed in Patent 2,552,882. It includes a hand wheel 04, index member 66 and drum scale 58 previously referred to in connection with Figure l. Referring particularly to Figures 8 and 10, hand wheel 64 has a forwardly extending handle |20 and on its rear face is provided with a bevel gear |22 that meshes with a second bevel gear |24 secured to a threaded rod |25. As best shown in Figure 10, the rod |26 is threaded through the index member B6, and the index member is provided with a forked end |28 that embraces a fixed guide rod |30, thereby preventing rotation of the index member with the threaded rod. Thus rotation of threaded rod |25 by hand when 6d moves index member 66 laterally with respect to drum scale 68.

As indicated in Figures 7 and 10, the drum scale |58 is provided around its periphery with a. series of scales having point sizes marked thereon, and the drum scale may be rotated by means of a manual knob |32 to present the desired scale for cooperation with index member 66, al1 as more fully described in Patent 2,552,882. The threaded rod |26 (see Figure 7) is connected by a series of shafts and gears generally designated |3-t with the line-length determining member 26, previously referred to in connection with Figure 1, and thus as the hand wheel 64 is rotated to cause index 66 to indicate the line length on drum scale 68, the line-length member 26 `is automatically positioned to the desired linelength determining position.

Still referring to Figures 7, 8 and l0, the index member 65 and drum scale 6B are located in a. housing |36, at the lower front left-hand portion of which there is provided a notched member |38 formed to receive the wall 94 of assembler slide 90 of the hand composing device. Referring particularly to Figure 8, in adjusting the guide 98 with respect to assembler slide 90, the wall S4 is inserted in notch |38 and the wall |00 ci' guide 93 is positioned opposite the index member t5. In this way the space between walls 94 and |00 can be made precisely equal to the decired line length.

the composing device I0, it is inserted in the machine in a manner now to be described.

Referring particularly to Figures 8, 9 and 10, se-` cured to the top of housing |36 is a channel member |50 which is attached to the housing in any suitable manner such as by means of the screws |52. As best shown in Figure 10, the channel member |50 is adapted to slidably receive the slotted support of the hand composing device I0 which is retained in place in the channel member |50 by a plate |54 secured to the channel by the screws |56 (see Figure 8) and overlying the channel. As illustrated in Figure 7 of the drawings, the composing device I0 slides into channel member |50 until its lefthand end strikes an abutment |56 :forming part of the elevator I2.

As previously pointed out in connection with Figure l, the composed line of matrices is raised to the level of a feed channel 22 by an elevator I2, the construction of which is best shown in Figures 3, 5 and 6 of the drawings. As best shown in Figure 5, the elevator is of U-shaped cross-section and comprises a front plate I 60 and a rear plate |52 spaced therefrom, the rear plate having at its lower edge a laterally projecting portion fi by means of which the two plates are secured together. Secured to the front plate |60 there is a handle member |55 which facilitates raising of the elevator I2.

Referring to Figure 3, the projecting portion |64 of elevator 2 is connected by a link |66 to the forward end of lever |68 which is pivotally secured to the desk 6. A spring |10 secured to the desk 3 is also secured to an intermediate point cf lever 58 in such manner that the spring exerts upward force on elevator |2. The tension of spring ma is so selected that it almost, but not quite, counter-balances the weight of elevator I2, link |66 and lever |68. Thus the ele- 9 vator I2 can be `raised by 'light vmanual pressure, but when lreleased descends of its own weight to its lower position.

Referring now to Figures 4, 5 and 6, the composed line of matrices is inserted into elevator |2 by manually grasping the curved end ,9B of assembler guide Sii and urging the left-hand end of `the assembled slide between the upper ends of plates |50 and |52 until the upper step III) of shoe |84 engages the end of slot 8d. The slot v85| is of such length that when it is engaged by the step I|0 the composed line will be properly positioned within the elevator.

As shown in Figure 5, the matrices are pro- "vided with upper ears I`|2 `and lower ears |14 L'that extend laterally beyond the sides of wall "94 of the assembler guide. The plates |50 and |62 of elevator l2 are provided with shelves |16 and |18 adapted to engage the Vlower ears litlof `the matrices, and are also provided with the shelves 18B and ,I'BI respectively, adapted to engage and support the upper ears |12 of the matrices. `Thus as the elevator is lifted the composed 'line of matrices is removed thereby from the assembler guide 9|), las `particularly shown in Figure '6.

.'Reverting now to Figure l, as disclosed in .'Patent `2,552,882, elevator I2 as it reaches its upper position engages and rocks the line-delivery lrelease lever 'I 4, thereby releasing 1line-fol `1ower20 `and 'line-delivery lever It for 'leftward movement. The relation between lever Id and line-follower 201is further shown in vFigures A14 16.` The `line-delivery `leverand line-follower are interconnected Vthrough a frame |82, having :wheels |`8l|that engage upper and lower horizontail trackswhich serverto 'guide the vline-follower l:along a horizontal path. The mounting of the iln'e-efollower 'is further disclosed in Figure 23 where Vit is shown that the wheels |84 run in :confronting tracks gor channels |85 formed in a :supporting frame |81 ,of generally C-shaped cross-section (see also'topportion of Figure '20). Reverting again to Figure .1, as line-follower 2i) moves to the Vleft 'it moves the vcomposed line of matrices from elevator I2 along thefeed chan- 'n'el'22 "to thejustifying station 21| where theline- "follower Aengages `and is Astopped by the linellength determining member 25.

"Referring new to Figure '3, the line-delivery lever 'I6 ispivotally mounted on desk 8 at |236 andis urged .ina countercloclswise direo'tionby ia relatively heavy spring |88 vthatis connected .iat ,one `end to desk Brand at'its other end to the deliveryleverat aA'point spaced frompivot iB. The deliverylever I6 .isprovided near pivot |86 with an `arm 'L90 connected by yalink A|92 to -a `conventicona-'l 'damping device |94 which clamps 'themovenrent Aofl the ldelivery vlever and prevents *excessive 'impact 'of the line-follower 2li on member at the 'end of the delivery stroke. It .may alsobe' noted-that a second damping device |96 isinounted Aon 'desk 8 and connectedto the :film "holder 32.

Interconnecting the two riders there is a control rail 20B that is pivoted to rider 202 and slidably pivoted to rider 206.

Referring now particularly to the left-hand portion oi Figure l5 wherein the line-follower 20 is Vshown in the ,position it occupies after most of a line of matrices, designated M-2, has been removed from the justifying station for photographing, the line-follower includes a pair of cooperating line-compacting members shown ign dotted lines. One of the line-compacting members is a vertically movable wedge 2|0v that is mounted v,for vertical sliding movement in suitable guides Fin the follower 20 and .carries at its lower end a roller 2I2. The wedge 2|0 is provided with a slot 2|4 engaged by a pin 2I6 that cooperates with slot 2id to limit the range of vertical movement o f the wedge. v

The other line-compacting member is a horizontally slidable plunger 2|,8 that is urged to the vright by a spring 220. The plunger 210 is provided with a head or ram 2,22 adapted to bear against the right-hand end of the line o f matrices M-2 `at the justifying station and carrying, within follower 20, a roller 224 adapted to engage lthe sloping surface 226 of wedge 2I0. The construction is such that upward movementl of wedge 2|0 causes plunger 2 I8 to move to the left and compact the 4matrices of the composed line against the end wall "C, previously identied. The amount of movement of plunger head 2 22 is equal to the line shortage referred to above, and hence the upward movement 4of wedge 2 I 0, which produces this leftward Amovement of plunger 2I8, is also a measure of the line shortage. The roller ,2 I2 and wedge 2L0 are moved upwardly by the rider 2M of movable rack 200 by mechanism which will presently be described.

As explained in my application Serial No. 177,145, the line shortage thus measured is used ,to modify movement of the nlm holder in such manner as to produce a justied line of type matter on the film. AIn my said prior application, itis pointed out that by proper adjustment of the riders 202 and r2|l it is possible to distribute this ljustifying correction over either the entire line or over a pre-,selected portion thereof. However, for purposes of the present discussion it will be sufficient to consider the case where .tlljllstifying correction is distributed over the entire line. For this case the vrider 202 is so positioned on rack 200 that .the pivotal connection o i the `rider and control rail 208 is aligned with thezaxisof rollerzlz. As shown in Figure 1, the control rail 20,8 is initially horizontal, but when the .rack 2 00 ,and rider v2112 are moved upwardly .by mechanism .presently ,to .be described the con- .trol railZEi Aassumes anangle that is proportional .t0 the line shortage.

'Upon completion ofthe line-compacting operation thephotographing apparatus is started and the feed rack `27 released. Thereupon matrices are transported from the'left end of the composed line at end wall C tolphotorgraphing position, andaseach matrix is removed thelinedelivery lever spring |08 moves the line-follower 20, line-determining member 2t and rackvZ-'l to the left and through mechanism 3S lowers the lml holder 32 a corresponding amount. As the oilowerZll moves to theleft, the roller 2 l2 rides downwardly .along the control lrail 203 thus `lowering' wedge2l0.A vRoller 224 ridesv along sur- 1 1 face 226 and the head 222 of plunger 2I8 is gradually retracted toward the body of the follower. As a result of this retraction of plunger 2 I8, each time a matrix is removed for photographing, the

`follower and feed rack 21 move to the left an amount slightly greater' than the thickness of the removed matrix and this small increment of movement is transmitted to the film holder in such manner that the justifying correction is distributed over the length of the photographed line.

The mechanism for moving rack 200 and rider 202 upwardly is best shown in Figures 17 to 20 of the drawings. As shown at the tcp of Figure 17, the movable rack 255 is secured to a crossbar 230 which (see Figure 19) is supported on a pair of vertical rods 232 and 234. are vertically slidable in holes in the bosses 236 and 238,respectively, which are fixed to the frame of the machine in a manner not shown in the drawings. The boss 233 is provided with a stop 240 which limits downward movement of crossbar 230. Below the bosses 236 and 238 the rods 232 and 234 are interconnected by a yoke 242 which carries a downwardly extending locking rod 244. A pair of springs 246 and 24S surround the rods 232 and 234, respectively, and are interposed between the yoke 242 and the bosses 236 and 238, respectively, in such manner that they urge crossbar 235 downwardly against stop 240.

Reverting to Figure 17, the locking rod 244 passes through a hole 250 in a locking member 252 that is provided at its left end with a downwardly projecting ledge 254 through which it rests on a xed abutment 256. The locking member 252 is urged in a clockwise direction around the pivotal contact between ledge 254 and abutment 256 by a spring 258 that bears against the upper surface of the locking member 252 and is held in place by a screw 260 which extends through the spring and locking member and is threaded into the abutment 256.

Referring now to Figure 20, the end of locking member 252 remote from ledge 254 is forked to receive the lower end of a control rod 262 which is pivotally connected to the locking member 252 by a pin 264. Near its upper end the control rod 262 passes through a guide block 266 that is secured to the main frame of the machine in any suitable manner such as by the screws 268. At its extreme upper end the control rod is provided with a block 210 that slides along an adjacent edge of guide block 266.

The upper portion of control rod 262 cooperates with a bell-crank lever 212 pivotally secured to the frame of the machine. Bell-crank 212 includes an arm 3I4 by means of which the bellcrank is actuated in a manner described hereafter and an arm 214 that is forked to partially embrace the control rod 262 between the portion of guide block 266 through which the rod passes and the upper block 210. The construction is such that counterclockwise rotation of lever 212 causes arm 214 to bear against the under side of block 210 to raise rod 262 and clockwise rotation of lever 212 permits rod 262 to move downward.

Reverting now to Figure 17, lifting of the cross bar 230 and its associated rack 260 is eiected by means of a manually operated control lever 265 provided at its cuter end with the knob 56 previously referred to and piv-oted by means of a pin 284 to the frame of the machine. At its inner end the control lever 280 has a rounded boss 286 that bears against the under surface of the cen- The rods 232 and 234 i tral portion of yoke 242. Thus, when the knob 56 is manually grasped and depressed, the yoke 242 is moved upwardly against the action of springs 246 and 248, and through rods 232 and 234 lifts the crossbar 23D which carries rack 200.

During the period when a line of elements is being photographed (and assuming that a justifying correction is to be made) the crossbar 230 is locked in its upper position by co-operative action or the locking rod 244 and locking member 252. As clearly shown in Figures 17 and 18, the hole 253 in locking member 252 is somewhat larger in diameter than the locking rod 244. When the parts are in the position shown in Figure 17 with the locking rod 62 in its upper position and the locking member 252 substantially horizontal, no locking action takes place. Under. these conditions if the knob 56 is depressed toraise crossbar 236 and then released, the crossbar will immediately be returned to its lower position in contact with stop 246 by the action of springs 246 and 246. The parts can be conditioned for locking by lowering rod 262 to the position shown in Figure 18, whereupon locking member 252 pivots about ledge 254 until the upper front edge and lower rear edge of hole 250 come in contact with and press against points on the surface of control rod 244. With the parts in the position shown in Figure 13 it is evident that upward movement ol' locking rod 244 with respect to locking member 252 will tend to pivot the locking member counter-clockwise and thus relieve the pressure betweenthe upper and lower edges of hole 250 and the locking rod; whereas if aneflortis made f to move the rod 244 downwardly with respect to locking member 252, the pressure between the parts will immediately increase to prevent such movement. Thus if the parts are in the position indicated in Figure 18 and the yoke 242 is moved upwardly by depression of knob 56 it will remain locked in its upper position upon release of knob 56, and until locking member 252 is rotated counterclockwise by upward movement of rod 262.

The control rod 262 is lowered to condition the A parts for locking by the line-delivery movement of the line-follower and is raised to prevent locking of the parts by the return movement of the line-follower at the completion of the photographing operation. The manner in which this movement of the control rod is effected will now be described. Referring particularly to Figureli, it has been previously pointed out that the control rod 262 is moved up and down by pivotal movement of bell-crank 212. The bell-crank 212 is in turn actuated by an actuating bar 300 mounted for lateral sliding movement on the main frame of the machinel The left-hand end of bar 300 is forked to embrace a pin 302. secured to the main frame, and the right-hand end of bar 300 is provided with a slot 304 which surrounds a pin 306 secured to the main frame of the machine. The bar 300 is urged to the left by a spring 308 secured to the main frame at 3I0 and connected at its other end to the pin 3I2 which Ais secured to the bar 300. Leftward movement of the actuating bar 300 is limited by pin 306 engaging the right-hand end slot 304. The longer arm 314 of bell-crank 212 is positioned to enga-ge the pin 312 of bar 360, and thus as the bar 300 moves horizontally it rotates bell-crank 212 to raise or lower control rod 262. The arm 3I4 is normally maintained in contact with pin 3|2 by the weight of control rod 262 and its associated parts as well as by spring 258." The relation 13 betweenpin 3| 2 and arm 3M of bell-crank 212 is well shown in Figure 20.

Referring now to the upper portion of Figure 20, the movable frame |82 on which the linefollower 2t is mounted has pivotally secured to the rear surface thereof a swingable detent 316, movement of which in a counterclockwise direction as viewed in Figure 20 is limited by the wall 318 of frame |82. Reverting to Figure 14 and particularly the right-hand portion thereof, the detent 313 is shown positioned against the wall 3IB of frame |82 and in engagement with a rearwardly extending arm ale of an adjusting member 320 that is adjustably secured to the bar 333. Member 32d is positioned for sliding movement along the rear surface of the end of bar 33] and is provid-ed with a slot 32| that is engaged by a guide pin 322 iiXed to bar 303. Member 320 is adjustably secured to bar 309 by means of screw 323 that extends forwardly through slot 32| and is threaded into bar 333, thereby permitting relative lateral adjustment of arm 3i9 and bar 303 and hence adjustment of the right-hand position of bar 330.

With the parts in the position shown in Figure 14 the line-follower 2Q and its associated frame |82 are held against leitward mov-ement by the line-delivery release lever i4, and the detent 3&3 through arm 3|9 holds actuating bar Stil at its right-hand position. Bar 33t through pin 312 maintains bell-crank 212 cocked to the right as shown and thus arm 214 of the bell-crank maintains the control rod 232 in its upper position and prevents locking of the justifying mechanism.

When the line-delivery release lever is rotated by upward movement of elevator l2, the linefollower 20 and its associated frame 82 move to the left to the position shown in Figure l5. With the initial movement of line-follower 23 detent 31B moves away from arm 319, thereby permitting bar 330 to move to the left under the influence of spring 308 and bell-crank 212 is rotated counterclockwise to lower control rod 232 and condition the locking mechanism for locking, As indicated in dotted lines in Figure 15 and also x shown in Figure 20, the swingable detent SIS engages and then passes over the top of arm 3M. of bell-crank 212 as the line-follower 2li appreaches the end wall C.

At the end of the photographing operation the line-follower 23, as more fully described hereafter, is withdrawn to its right-hand position as shown in Figure 14, and this withdrawal of the line-follower ill] and its associated frame |82 causes the detent 3|6 to engage the arm 3M oi bell-crank 212 to cause it to pivot clockwise and raise control rod 262 thereby unlocking the juslfyng mechanism. As the line-follower reaches its right-hand position, the detent 3|@ again engages arm 3l3 of bar 3M and. draws the bar to its right-hand position as shown in Figure la. The pin 312 then maintains bell-crank 252 cocked to the right to maintain the control rod 232 in its upper or unlocked position.

The justifying apparatus ci the present machine, like that of application Serial No. 177,1455, is constructed to permit arrangement of short lines at either the left margin of the column of type matter (flush left operation), or at the right margin of the column of type matter (hush right f operation), as well as to permit the normal justiication of a full line. As explained in application Serial No. 177,145, in order to achieve flush right operation the cross bar "23d is left Ain itsv lower position, and this type of operation can be achieved in the present machine merely by not depressing the lever 56. In the initial description of Figure 1 a brief reference was made to the lever 58 which in its upper position provides for normal justifying operations and in its lower position provides for iiush left operation. In the present machine flush left operation is achieved in essentially the same manner as described in application Serial No. 177,145, namely by bolting the control rail 238 to the crossbar 230 so that as the crossbar 230 is lifted the control rail remains horizontal.

Since the structure for bolting the control rail to the crossbar 23@ is the same as that disclosed in my said prior application, it is not fully shown in the drawings of the present case. However, a portion of this structure is shown in Figure 1'7. Referring to that figure, the lever 55 is indicated in phantom view and is mounted on a rotatable shaft 333 to which is secured a sprocket 332 which is engaged by a chain 334. When the lever 58 is moved .from its upper to its lower position, sprocket 332 rotates to move chain 334 to slide a bolt (not shown) carried in crossbar 230 into engagement with control rail 208 so that when the lever 2353 is depressed to raise crossbar 23? the control rail 238 rises horizontally. Referring to Figure l5, when the control rail is raised the line of elements IVI-2 is compacted as previously described, but upon release of feed rack 2i the roller 2ER travels along a horizontal path and hence no justifying correction is applied to movement of the film holder.

When the lever 38 is raised to its upper position, the chain 331| moves in the opposite direction to withdraw the bolt from control rail 20B to permit the normal justifying operation as previously described.

The photographing apparatus The photographing apparatus of the present machine is essentially the same as that disclosed in Patent 2,552,882 and hence is not shown in detail in the drawings nor described in detail herein. In general the photographing apparatus includes a pair of endless chains for raising the matrices of the line M-Z individually to a photographing position at which the characters thereon are photographed and then to a discharging position from which they are discharged on the accumulator bar 33 (see Figure l) The photographing apparatus also includes lens means and movable shutter means which with the conveyor chains and other moving parts of the photographing apparatus are driven through a clutch by a continuously operating electric motor. In the patented machine this clutch is actuated by a earn; whereas in the present machine actuation of the clutch to start the photographing mechanism is effected by manual movement of accumulator bar plate 31E in a manner which will now be described.

As previously indicated in the Brief description. oi the machine, lowering of the plate 33 not only moves the camera drive clutch to engaged position but also releases the feed rack 21. The structure for effecting these operations is shown in Figures 22 to 26 of the drawings. Referring first to Figure 22, the plate 33 is hinged at its rear edge to the main frame or" the machine at 340 and is provided at its front edge with a pivoted handle 3%. The lower end oi handle 352 is provided with a hook 3M that is adapted to engage a latch member 333 (best shown in-Figure l1) to maintain the plate 3d in its lower closed position.

The wedge member 314 is moved clockwise toymove interponent 388 out from under rod 350 by a bar 318 in a mannernowto be described.

Referring particularly to FigurelLthe bar 318fis-pvotally connected at spaced points to the lower ends ofia pair of parallel links 380 and 3112y which are in turn pivotally supported at their upperendsonthe main frame of the machine in suchmanner. that the bar 318 is free to swing laterally; Theline-follower `211` is provided with a forwardly extending arm lwhich, as the line follower approaches line-length-determining member` 26,? lifts and passes under a latch 29 pivotally` mounted on member 25, therebylatching the line-follower to member 26. The 1atch;29 is aligned: with bar 31B `and when it` isyraised by arm21 of the line-follower itengagesbarf318rand swings the bar 'upward to the left. Thebar 318 thereupon: engages and rotates wedge` member 314aspreviously described to condition the feed `rack releasing mechanism to permit the feed rack to,v be released when cover plate 34 is lowered.

In order to maintain the bar 318 ,in its lefthand, position until the line-follower has been retracted after completion of the photographing operatiomdetent mechanism is provided which is showniin Figures 11, 12 and 13. As best shown iniFigurell, the upper end of link 382 is provided with a shoulder or notch 394 whichlsee Figure 12)` is adapted to be engaged by a pivoted arm or detent 386. The arm 386 is pivotally connected between its ends to one end of an axially slidable rod 388that is mounted for sliding movement inithe brackets 390 and 392. Interposed between bracket 3911 and the left end of rod 338 and surrounding the rodthereis a` spring- 394 biased to urge the rod ato .the left.
